Is this sentence grammatical?
"私はいつ六才に幼稚園にいました。"

"When I was 6 years old, I was in kindergarten."

I am wondering how to say sentences like "When I was X years old, I did _____ or was in _____.

Thanks in advance, Cole

Answer

instead of いつ6才に you have to say 6歳の時 (ろくさいのとき)

good luck!

Answer

私が6歳(it’s also OK with 六才)の時、私は幼稚園にいました。

Answer

We never say　幼稚園にいた、大学にいた、and double私は is wrong too.

私は６歳の時に幼稚園に通って（かよって）いました。

Answer

The way I phrased the question is also grammatically correct. They are both grammatical.
